About this food
How to think about Meat & Protein: Fish is worth a closer look - Animal proteins tend to be higher in phosphorus, and animal phosphorus absorbs at 60-80% versus 30-50% for plants. Choosing low-phosphorus proteins such as egg whites or tofu, or controlling portions of red meat, is a common CKD approach.
Nutrient insight
On the phosphorus angle (25%), Fish belongs in the watch category. Pairing it with low-phosphorus sides like white rice or egg whites balances the meal.
Other nutrients
Protein24.4 gNot rated; needs attention at stage 4-5
Fiber0 gBeneficial for CKD (core plant-based nutrient)
A common practice is: Boiling meat first and discarding the water removes some phosphorus and potassium; prefer low-phosphorus proteins like egg whites.
Combining phosphorus, sodium and potassium, Fish falls in the Limit tier, with Phosphorus (25%) contributing the most. Plan meals with your doctor's guidance.
Why is Fish rated Limit?
The deciding factor is Phosphorus: 254 mg, 25% of the limit, in the 25-30% band - so Fish is rated Limit.
How much Phosphorus is in Fish?
Per 100 g, Fish provides Phosphorus 254 mg, compared with the CKD stage 3-4 limit of 1,000 mg (25%).
Is Fish safe on a low-potassium diet?
On a low-potassium plan, Fish exceeds the 300 mg reference, showing 486 mg of Potassium per 100 g. Individual targets vary by CKD stage and lab results.
How does Fish compare to other meat & protein foods?
Within Meat & Protein, Fish ranks more on Phosphorus (254 mg per 100 g) than the group average. Individual needs still decide what fits your plan.
